About transparency knockouts
You use the Knockout Group option in the Transparency palette to make every object of
the selected group or layer knock out—that is, visually block out—the other objects in the
group or layer that it overlays. Only artwork within the selected group or layer is knocked
out. Objects beneath the selected group or in different layers are still visible relative to the
group or layer.

You can also control the interaction of transparent fills and strokes within an object if the
transparency is applied directly to the fill or stroke in the Appearance palette. To do this,

Creating transparency knockouts
Selecting the Knockout Group option cycles it through three states: on (check mark), off
(no mark), and neutral (gray or dash). Use the neutral option when you want to group
artwork without interfering with the knockout behavior determined by the enclosing
layer or group. Use the off option when you want to ensure that a layer or a group of trans-
parent objects will never knock each other out.
